Opportunity cost is the difference between the nominal and real cost of some action

The above figure shows the payoff matrix for two firms, A and B, choosing to produce a basic computer or an advanced computer. The mixed-strategy Nash equilibrium is

A) Firm A produces an advanced computer with 80% chance, firm B produces an advanced computer with 20% chance. B) Both firms produce advanced computers with 50% chance. C) Firm A produces an advanced computer with 60% chance, firm B produces an advanced computer with 40% chance. D) Both firms produce advanced computer with 80% chance.

Is it possible for a firm to have a comparative advantage in producing something without having an absolute advantage? Why or why not?

What will be an ideal response?
